This interview focuses on a subset of the global warming issue which was unfamiliar to me: the warming of the oceans. And it?s not just temperatures that are affected by the waters? absorption of enormous amounts of carbon dioxide; the ocean chemistry is changing, and organisms at the bottom of the food chain are disappearing. While the topic makes me stop and listen, this piece does not always hold my attention as a piece of radio. The interviewee is a scientist from the Woods Hole Oceanographic Institution, and while he's very knowledgeable about the topic, he does not have an engaging manner of speaking. The interviewer Christopher Lyden tries to infuse energy into the conversation, but with only partial success. Some questions work while others are not as focused and succinct as they could have been. I appreciate that this piece brings an important topic to my attention, and hope it?s explored further through sound-rich feature stories as well as through interviews.
